A large selection of Thimble Theatre characters have blink and you'll miss it cameos in this cartoon:
Cole Oyl, Olive Oyl's Dad makes a very rare appearance, he can be seen poking his head out of the bottom left window after Bluto leaves the apartment building.
In the window to the right of Cole is Nana Oyl, Olive's mother and directly above the door appears to be Ham Gravey, Olive's original boyfriend.
The last cameo is Popeye's driver, Oscar, a friend of Popeye from the comics.
The truck Bluto uses to gain entry to the apartment building would also be used by Humphrey Bogart in The Maltese Falcon (1941).
Wimpy, as usual, has one eye on his supply of hamburgers.
Both Latin and Russian music and dance were extremely popular at the time of this short, as can be seen (and heard) here.
The short's title is a pun on the musical overture by Franz von Suppé, Morning, Noon, and Night in Vienna, first performed in Vienna back in 1844.
